It would be expensive and difficult to separate it out into grades in order to control the quality of what's being produced. At our place we have constant problems with porosity in foreign castings, but the British foundries we used to use have closed down. I've seen components costing tens of thousands with scrap stickers on them due to porosity.
Thanks for posting that MrB. I hadn't realised the implications from that perspective (although I knew they were bad!).

Searching a bit further, I came across this explanation which puts it in laymen's terms I could grasp better.

"Blast furnaces make iron which feeds the steelmaking process and electric arc furnaces make the steel. Port Talbot will stop making iron.

Think of bread. The blast furnaces make the flour and the electric furnaces make the bread. If you start with bad flour you get bad bread.

The electric arc furnaces will use scrap flour, of unknown quality. The bread will be of poorer quality. The output has thereby been downgraded. Most of the scrap comes from China – but not the iron ore which makes the iron. Therefore, we continue the dependence on China. Politically bad".

This comes from the comments section of https://unherd.com/thepost/european-...ping-net-zero/

Nut-Zero = Unilateral Economic Disarmament in favour of China, Russia and India - what could possibly go wrong?
